Conversion from String to MongoDB ObjectID

Question

I tried converting my String ID to MongoDB ObjectID

public class relevancy_test extends  Object implements Comparable {
    public static voi         


        

Answer 1

While retrieving from List cast it directly to ObjectId

 for (DBObject postObj : dbobj) {
        ObjectId objId = (ObjectId)postObj.get("_id");
        updateMap.put(objId, postObj);
}
